C-x ESC ESC now suffering from premature expansion?

[Dan Jacobson]

Am I correct in remembering back in emacs 20, when we did
M-x something
and then
C-x ESC ESC   [which is repeat-complex-command]
it would do the same something again.

But now, say do
M-x font-lock-mode RET [just an example, nothing personal against
font-lock-mode, I just need a toggler example]
C-x ESC ESC RET
C-x ESC ESC RET
C-x ESC ESC RET...
notice how only the first line changes anything, the rest don't as the
invisible parameter was already written into the history...

OK, so now I will rewire my brain [age:41, please don't do this that
often to me.  we hear that computer programmers are mainly good up to
age 45, so pass the Geritol] to do
M-x M-p
[however it apparently can't reach back to all the many other things
C-x ESC ESC can...]

Interesting: do
M-x font-lock-mode
C-x ESC ESC RET
C-x ESC ESC RET
C-x ESC ESC RET...
we are stuck with the "gratuitous" parameter at the end of the line, so:
C-x ESC ESC [now edit that parameter out] RET
C-x ESC ESC RET
C-x ESC ESC RET
C-x ESC ESC RET...
ah, much better.  Doesn't fix M-x yow though.  For that one must use
the M-x M-p method.  You [or I at least] are not going to get any
jollies from C-x ESC ESC after a previous m-x yow, now way, no how [?]

anyways, "the consumer obviously typed X, I think we should give him X
and not X 0 0 back" etc.
